I enjoyed this little thriller. The acting is decent enough, the pacing is good, and it certainly has the pre-war atmosphere. Dialog is good, even snappy at times. Most of the action is in the form of stock footage of Shanghai being bombed by the Japanese. I recognized a number of Chinese actors, including child actor Layne Tom, Jr., who is uncredited in the movie, at IMDb and Wikipedia
. He was in several Charlie Chan movies as various sons, and got to say 3 sentences in this one.
I downloaded the 512Kb MPEG4 file. Video quality was adequate, the audio was fine.
